Panel 1: Bilbo Baggins ponders, “After all… why should I care about the difference between int and String?
Panel 2: Bilbo Baggins is revealed to be an API developer. He continues, “JSON is always String, anyways…”
To whoever does that, I hope that there is a special place in hell where they force you to do type safe API bindings for a JSON API, and every time you use the wrong type for a value, they cave your skull in.
Sincerely, a frustrated Rust dev
“Hey, it appears to be int most of the time except that one time it has letters.”
throws keyboard in trash
Rust has perfectly fine tools to deal with such issues, namely enums. Of course that cascades through every bit of related code and is a major pain.
Sadly it doesn’t fix the bad documentation problem. I often don’t care that a field is special and either give a string or number. This is fine.
What is not fine, and which should sentence you to eternal punishment, is to not clearly document it.
Don’t you love when you publish a crate, have tested it on thousands of returned objects, only for the first issue be “field is sometimes null/other type?”. You really start questioning everything about the API, and sometimes you’d rather parse it as
serde::Valueand call it a day.API is sitting there cackling like a mad scientist in a lightning storm.
True, and also true.
This man has interacted with SAP.
Relax, it’s just JSON. If you wanted to not be stringly-typed, you’d have not used JSON.
(though to be fair, I hate it when people do bullshit types, but they got a point in that you ought to not use JSON in the first place if it matters)
As if I had a choice. Most of the time I’m only on the receiving end, not the sending end. I can’t just magically use something else when that something else doesn’t exist.
Heck, even when I’m on the sending end, I’d use JSON. Just not bullshit ones. It’s not complicated to only have static types, or having discriminant fields
You HAVE to. I am a Rust dev too and I’m telling you, if you don’t convert numbers to strings in json, browsers are going to overflow them and you will have incomprehensible bugs. Json can only be trusted when serde is used on both ends
This is understandable in that use case. But it’s not everyday that you deal with values in the range of overflows. So I mostly assumed this is fine in that use case.
